So all these people who keep saying Sony should bring back old IP even though the original development studios aren't around think that Sony shouldn't find new studios to do the games? In this case while Supermassive is still around, another company owns them and this was made by former supermassive developers.
Making games is difficult, you can be competent and well intended and things still don't work out for one reason or another. The game had a deadline, it's clear Sony didn't want to sink more money into it, and we get what we get.
That's life.
